BIB-COCK.

SPECIFICATION formingpart of Letters Patent No. 687,544, dated November 26, 1901.

Application filed February 21, 1961- Serial No. 48,205. No model.)

This invention relates to certain new and useful improvements in bib-cocks, and has for its object the provision of novel means whereby the different parts may be easily taken apart and replaced with the new parts when the occasion requires; furthermore, to provide means for attaching and detaching the bib-cock without the necessity of forming a wipe-joint for such attachment.

It has been found that in the use of bibcocks such as are attached to the flow-pipe by means of wipejoints when the valve-seat becomes worn it necessitates the removal of the body portion of the bib'cock and likewise requires the removal of the wipe-joint in order to replace the bib-cock. In many instances when the valve becomes worn a new one cannot be easily substituted, as it becomes necessary to replace the same by an entirely new bib-cock.

All of the above-mentioned difficulties are effectually overcome by the use of my improved bib-cock; and the invention resides in the particular construction, combination, and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and where in like numerals of reference indicate corresponding parts throughout the several views, in which-- Figure 1 is a vertical sectional view of my improved bib-cock,showing the same attached to the supply-pipe. Fig. 2 is a side elevation of the valve-casing. Fig. 3 is a top plan view thereof. Fig. 4 is a side elevation of the valveca-sing, showing the same in another position from that illustrated in Fig. 2 of the drawings. Fig. 5 is an inverted plan view of the same. Fig. 6 is a perspective view of the same. Fig. 7 is a perspective view of the removable head.

In the drawings the reference-numeral l indicates the supply-pipe; 2, the wipe=joint, connecting the section of pipe 3 to the supplypipe 1. This section of pipe 3 is exteriorly screw-threaded, as shown at 4, to receive the casing of the bib-cock 5, in which is arranged the valvecasing 6, carrying at its upper extremity the upper face 7, formed integral therewith, said face 7 having formed therein screw-threaded apertures 8 to receive the head 9,having a central opening 10 and outwardly-extending lugs 11, which are likewise formed with screw-threaded apertures 12 for the reception of screws 14, which engage the screw-threaded apertures S of the upper face and secure the head upon the valve-casing. The lugs 11 are adapted to fit in recesses 15, formed in the upper portion of the casing.

The reference-n ulneral 16 indicates interior screw-threads formed in the valve-casing to receive the screw-threaded portion 17 of the valve 18, carrying the valvestem 19, extending through the opening 10 of the head.

The reference-numeral 20 indicates a valveseat secured in the casing, against which the valve 18 operates.

The reference-numeral 21 represents an opening formed in the lower portion of the valve-casing, which is adapted to register with the outlet of the bib-cock in the interior of the casing.

The reference numeral 22 represents a washer arranged over the head 9, and 23 indicates a cap,the latterloeing interiorl y screwthreaded, as shown at 24, and is secured to the upper end of the casing 5 of the bib-cock. This cap 23 is also provided with screwthreads 25 at its upper extremity to engagea jam-nut 26, the upper portion of said cap and lower face of said jam-nut being recessed, as shown at 27, to receive the packing 28.

The operation of my improved valve will be readily apparent from the foregoing description, and it is thought that a further detail description is unnecessary.

In case the valve becomes worn it will be seen that the same may be easilyremoved from the valve-casing and repaired and may then be again readily replaced to its proper 7 position.

In order to remove the valve-casing, the parts may be easily detached and a new casing replaced when the occasion requires. When the bib-cock becomes worn, the same may be easily detached from the pipe 3 and a new one inserted in its place.

It will be noted that various changes may be madein the details of construction Without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a bib-cock, the combination of a flowpipe, a section of pipe secured thereto, a removable casing, a removable valve-casin g se- In testimony whereof I affix my signature in the presence of two witnesses.
